In spite of it's rather basic nature, the concept of ownership is a particularly sophisticated and abstract concept.  Ownership ultimately depends upon moral understanding and principles and not upon force.

There is nothing that can happen or be done to a piece of property that will reveal to you with certainty who the owner of the property is, or whether the property is owned at all.

Having your name clearly engraved on an object will not absolutely assure you that a stranger will know by this mark and process that the item is yours.  Properties with a name firmly and clearly affixed have and are frequently sold to others - by their owners. 

A name of someone other than the owner can be engraved upon the item, perhaps fraudulently by someone else in an attempt to claim ownership of something rightfully owned by another. The existence of the name of a person upon a property does not prove ownership.   It may be helpful, but is never conclusive.

There is also such a thing as partial ownership, or shared ownership, as we have already examined. 

An example of this might be a case in which credit is involved in the purchase of an item of property.  You buy a house, or a car.  To do so, you borrow the use of some money from a lending agency or another individual. 

You provide the lending agency with a mortgage or lien, indicating that while you have the house or car in your possession for your use, you do not yet totally own it.  The lending agency still has an ownership interest in the property, as their money was used to enable its purchase.

We might say in such a case that you are in the process of obtaining and establishing ownership.  Only when you have fully paid for the house by fully re-paying the lender the amount of money borrowed (plus an amount of interest or fee for having had use of the "rented" money), will the ownership rights of the lender cease completely.
